Evidence limitation
Automated conformance checks are not complete accessibility evidence
Direct limitation
Automation cannot reproduce every assistive technology, disability interaction, interpretation or user need.
Artifact or claim that may be supported
Static and browser automation can detect many structural, reflow, focus, contrast-adjacent and rendering defects.
What the evidence does not establish
Automation cannot reproduce every assistive technology, disability interaction, interpretation or user need.
Additional evidence required
A PASS can be overstated as universal accessibility.
Mitigation
Publish the test scope and preserve independent manual assistive-technology review as a known limitation.
